Dr. Merritt always is very thorough and addresses all our questions and concerns! She comforts Lucas when he feels sick and gets him on the track to getting well! She was the first Specialist we seen when we moved here from Oklahoma and she got the right test ordered and we got a correct diagnosis and treatment plan ! I am thankful she has been here for us through this journey!
